Definition of wollastonite in English:

noun

The Badger Flats area is also well known for clinozoisite, garnet, hematite, scheelite, vesuvianite, wollastonite, and zoisite (variety thulite).

The skarn layer has a massive texture with two assemblages, wollastonite + quartz + diopside and prehnite + datolite + actinolite + K - feldspar, which have been interpreted as evidence of hydrothermal metasomatism of carbonate rocks.

The groundmass of these leucocratic segregations is heterogeneous, consisting of centimeter-scale regions dominated by nepheline, natrolite, alkali feldspar, or wollastonite.
